het, I,

To' azz'km'zmay'aneem-- Be it known that I, WnmM1G`.-Fonnr1}ro, a citizen-of the United States, residing at Cleveland, in the countyof 'Cuyahoga' and S tate of Ohio, have invented a certalniiew` fore. been used or proposed, but it is found that they have `defects chief vof whichv is that they vareliable to stick, becaus'ejo the corrosive actionof theV liquid found in such wells, vsuch liquidbeing usually ofsuch a.

'; natureas to cause corrosion of metallparts immersed therein.

011e.- of theobjects of the present inveni tion is to provide a simple and ecient valve having a fof nished' surfaces', such 'as would if' corroded be liable to cause stickfv ing of the valve, aliberal clearance for corrosion .being provided between the An ioiz'able Y Y -alnce with my invention, the valves being larranged at intervals in the length of the 85 vparts 'ofthe valve.

' A further? object is to providea series .of s uehvalves. placed at intervals in theliquid 'pipe line and so arrangedthat they may be eiliectively opened or vclosed in-succession.

f In the accompanying sheet of drawings tudinal section of one of the blow -valves in its open position, and of the well casing around the same; Fig. 2 is a horizontal seclongitudinal sectional view of the blow valve in vits closed position; Fig. 4' is a sectional view ofthewell provided with my invention; and Fig. 5 is a detail partlyin section' of the hoisting and lowering devices at the top of the liquid pipe line. Y In the drawings, the ,gas well casing is indicated at 1, and from this casing, there 75 is led off asgas main 2 having a Avalve 3.

its upper end with a valve 5 tovcontrol the 1 flow of liquid therethrough. This liquid pipeline is composed of a number of relatively, movable sections-connected or coupled together by valves constructed in accordliquid pipe line. The different sections of the liquid pipe line are adapted to be successively raised or lowered to close and open the valves by raising and lowering mecha'- ence to this gure, it will be seen that a cap This cap 6 is connected by parallel rods? Clamped to the liquid ,pipe ,line by clamps 1 1 and clamping bolts 12 :is a-threaded sleeve 13'provided .atv

One of t e main features of .my invention resides in the. blow valve itself which connectseach pair of the relatively movable sections of the liquid pipe line 4. The num;` ber of these pipe sections and number` of -blow valves can be varied to suit'the .rei

quirements of any particular case, the num- Y ber usually depending upon local condi-- tions, e., the conditions ofthe locality in which the well is located. By referenceto Figs. 1,2 and 3, itwill be observed that the lower end of each pipe section is united by a reducing coupling 19 to an 'inner tubular valve member-'20 having a reduced middle portion, and externally tapered or conical -lower end portion 20a, the latter having fa finished outer tapered or conical surface'21, land the lower 'end of the coupling 19 having a `tapered or conical finished surface 22. The 'surfaces 21 and 22 oni the overhanging orv shouldered parts constitutein effect seats which are vengaged by 'thefother coperating part of the valve.vr

A valve caslng 231.coperates-withxthe vparts just described-to form'the valve'and the coupling yor connection bletween two ad,- jacent pipelinesections. This casingf'23 at sleeve 2385130 fthe upper end oflv the" tion,.and at its upper end is provided:withl end of the valve member 20 and is provided with a finished inner tapered or conical surface 24 cut on the` same .taper as the suiface 21 .of the valvemember 20', and adapted-- to oengagethe latter.- A At its upperend,l this casing has' a'giinished surface 25 which is" adapted to engagethe finished surface 2 2 facethereof engages'the ftapered surf,

wellmay build up,.and if the valve 5 inthev liquid 1 pipeline is opened and gas iiows through the valve 5,'v it is .apparent that the uppermo'stfvalve or valves ofthe lq ld .pipe line are not immersed in the liquid. If this occurs, by turning the' 'nut 14' on the threaded sleeve .13, the liquid pipe line is raised sufficiently to successively 5 close the uppermost valve or valves until all' .the valves l above the .liquid --in the well are closed.. Then the gas pressure forcesthe liquid through theportsor openings 26 of f the uppermost openv valve which is below .the level of the liquid, and. forcesthe liquid up -through the pipe line vand 'out of the well, lAfter the liquid above said open Aval'vefei's forced I from the 'well, the pipe linewillzbe .raised stillffurther, closing from .the well;
